Summary

Because prevailing atmospheric/troposcopic conditions greatly influence radio wave propagation above 10 GHz, the unguided propagation of microwaves in the neutral atmosphere can directly impact many vital applications in science and engineering. These include transmission of intelligence, and radar and radiometric applications used to probe the atmosphere, among others.

Where most books address either one or the other, Microwave Propagation and Remote Sensing: Atmospheric Influences with Models and Applications melds coverage of these two subjects to help readers develop solutions to the problems they present. This reference offers a brief, elementary account of microwave propagation through the atmosphere and discusses radiometric applications in the microwave band used to characterize and model atmospheric constituents, which is also known as remote sensing.

Summarizing the latest research results in the field, as well as radiometric models and measurement methods, this book covers topics including:

Methodology of estimating water vapor attenuation using radiosonde data

Knowledge of rain structures and use of climatological patterns to estimate/measure attenuation of rain, snow, fog, and other prevalent atmospheric particles and human-made substances

Dual/multifrequency methodology to deal with the influence of clouds on radiometric attenuation

Deployment of microwaves to ascertain various tropospheric conditions

Composition and characteristics of the troposphere, to help readers fully understand microwave propagation

Derived parameters of water, free space propagation, and conditions and variable constituents such as water vapor and vapor pressure, density, and ray bending

Author(s) Bio

Pranab Kumar Karmakar obtained his MSc in physics in 1979 and PhD in the area of microwave propagation and remote sensing in 1990 from the University of Calcutta, India. Associated with the Department of Radiophysics and Electronics at Calcutta University since 1988, he is involved in both teaching and research work. He has more than forty-five publications in national and international journals of repute. Karmakaralso has more than thirty conference articles to his credit. He was awarded the Young Scientist Award of URSI (International Union of Radio Science) in 1990. He has been a visiting scientist at the Remote Sensing Lab, University of Kansas; Centre for Space Science, China; and Satellite Division, National Institute for Space Research (INPE), Brazil. He has also been awarded the South-South fellowship of TWAS (The Academy of Sciences for the Developing World) in 1997.

Karmakar’s current area of research includes microwave/millimeter wave propagation, microwave remote sensing, and atmospheric modeling.

What does "CPD Certified" mean?

CPD consists of any educational activity which helps to maintain and develop knowledge, problem-solving, and technical skills with the aim to provide better health care through higher standards. It could be through conference attendance, group discussion or directed reading to name just a few examples.
